[TYPO3-core] RFC #14090: importExtInfo() does not sort versions correctly

[Steffen Gebert]

Hi all,

This is a SVN patch request.

Type: bugfix

Branches:
trunk, 4_3

BT reference:
http://bugs.typo3.org/view.php?id=14090

Problem:
In Extension import submodule of the EM, showing the details of an  
extension sometimes shows an old version as the newest one.

Solution:
use natsort to sort the version numbers and use the last list entry as  
default since it is the highest one.

Note:
The same issue has been fixed with #14003 "Check for extension updates"  
does not always find latest version, so it's quite dizzying when you want  
to install this newest version, but EM installs an old one for you ;-)
I've posted some more details of EM internas in BT entry.

Credits go to Daniel Minder

Thanks
Steffen
